Vegetovascular dystonia (or VSD for short) is a psychosomatic problem in which the functioning of the autonomic system, which is responsible for balance in the body, is disrupted. At the same time, the circulatory system “fails”, blood pressure and vascular tone decrease - therefore, all organs receive the necessary substances in smaller quantities than required. This leads to disastrous consequences, such as blood stagnation, brain hypoxia, and decreased organ activity. One of the varieties of this disorder is VSD of the hypotonic type. It is characterized by disruption of the cardiovascular system, decreased blood pressure, and decreased blood flow to all organs.
Young people who lead a sedentary lifestyle are more often susceptible to VSD of the hypotonic type. But this type of vegetative-vascular dystonia can also affect the older generation.
Types of vegetative-vascular dystonia (VSD)
Depending on how the cardiovascular system reacts to a disorder of the autonomic nervous system, 4 types of VSD are conventionally distinguished: hypertensive, hypotonic, cardiac and mixed. A more detailed study of the signs of vegetative-vascular dystonia made it possible to identify 3 more types of disorder: vagotonia, cerebral-type VSD and somatoform dysfunction.
This typology is outdated, however, it allows you to classify all symptoms of VSD. The problem of diagnosing autonomic dysfunction is acute, and patients often become victims of ignorance or inattention of doctors. Let's figure out what symptoms may indicate the presence of one or another form of autonomic dysfunction.
Clinic of the disease
Most often, at the beginning of the development of a pathology such as neurocirculatory dystonia, symptoms appear weakly and do not directly indicate damage to the autonomic system. The most common nonspecific symptoms are:
- headache;
- severe weakness;
- sweating;
- drowsiness;
- tinnitus and dizziness;
- panic for no reason;
- fainting and a feeling of impending loss of consciousness,
- mood swings;
- anxiety;
- changes in the functioning of the heart, manifested by a decrease or increase in heart rate;
- surges in blood pressure and temperature.
- Sleep disorders
An attack of neurocirculatory dystonia may occur: symptoms will include severe weakness, nausea, hypothermia, headache, abdominal discomfort, hypotension, sweating, etc.
In people over 50 years of age, exacerbation of neurocirculatory dystonia is often more pronounced: symptoms will be more varied and often include signs of existing chronic diseases.
VSD of cardiac type
In the cardiological (as well as in the hypertensive) form of autonomic dysfunction, the diagnosis will most likely show obvious sympathicotonia, that is, functional tension in the work of the sympathetic department of the ANS. A distinctive feature of VSD of the cardiac type is pain in the heart area (stabbing, pressing or burning sensations in the chest area). Signs may resemble those of an angina attack or myocardial infarction. But upon examination, cardiac pathologies are not detected.
The cardiac type of reaction to a vegetative-vascular disorder is characterized by: tachycardia, cardiac arrhythmia, false pain in the heart area, as well as respiratory arrhythmia and asthma attacks. It is important to understand that with VSD, pain in the heart area is not a harbinger of a heart attack and does not in any way affect the cardiovascular system, which will be confirmed by the patient’s echocardiogram. Cardiac rhythmography is very effective in diagnosing this type of VSD.
Diagnostics
Diagnosis is based on characteristic patient complaints and examination data. Usually, in addition to standard laboratory examinations, an ECG is taken at rest and during exercise, electroencephalography, radiography of the spine, and ultrasound of internal organs.
ECG is one of the diagnostic methods
The functional nature of the disease, which does not have clear manifestations, usually does not allow its specific signs to be detected during examination. The diagnosis takes into account the sum of many indirect signs.
Consultations with a neurologist and other doctors of related specialties are important for diagnosis.
VSD of mixed type
Depending on how the cardiovascular system reacts to a disorder of the autonomic nervous system, the 3 types of VSD described above are conventionally distinguished. But, as a rule, vegetative-vascular dystonia includes several types of symptoms at once.
The mixed type is characterized by a combination of the above symptoms. Blood pressure “jumps”, a person feels sometimes depressed, sometimes irritated, sometimes experiences weakness, sometimes excessive emotional overexcitation, and his mood changes sharply. With a mixed type of VSD, the whole spectrum of symptoms can manifest itself: cardiac and respiratory arrhythmia, panic attacks, pain with vague localization. This type of autonomic disorder is the most common.
There are main types of neurocirculatory dystonia:
- hypotonic type (the main disorders in this case are associated with a decrease in blood pressure);
- hypertensive type (characteristic changes in blood pressure with a tendency to increase)
- cardiac type (accompanied by disturbances in cardiac activity, increased or decreased heartbeat, as well as discomfort in the chest, etc.)
- mixed type (when it is difficult to classify changes in the body; in this case, a variety of complaints and symptoms are characteristic).
VSD of vagotonic type
Vagotonia is characterized by a wide variety of symptoms, which can raise suspicion of serious diseases of the heart, endocrine or respiratory system, diseases of the gastrointestinal tract or even the psyche. A thorough examination does not reveal any pathologies in the organs and systems of the body. And as a “diagnosis of exclusion,” the patient is diagnosed with “VVD of the vagotonic type.” Indeed, a variety of symptoms that do not fit into a single pathological process are caused by vagotonia - hypertonicity of the vagus nerve (“vagus”). The vagus nerve regulates the activity of organs, glands and blood vessels, and an increase in its tone causes spasm of smooth muscles throughout all structures of the body.
With this type of VSD, the activity of the parasympathetic part of the nervous system predominates (over the sympathetic), which will be confirmed by the diagnosis of CRH. A person becomes apathetic, unsure of himself, suspicious, suffers from hypochondria, suspecting that he has the most terrible and, perhaps, still unknown disease. Memory for specific things often deteriorates: numbers, dates, details, and mental activity decreases.
Physical symptoms are bradycardia, hypotension, vestibular disorders (dizziness and fainting), fatigue, shortness of breath, pale skin, cold extremities, non-localized pain in the abdomen and chest. Despite the broken state, the person experiences difficulty falling asleep and does not sleep well during the night. In advanced cases, patients experience panic attacks, depression and suicidal tendencies. Symptoms can appear in a complex manner, or they can be localized - when complaints are limited to one of the organ systems. The disease can be chronic or manifest itself in the form of outbreaks, vegetative crises, when the condition sharply worsens. In vagotonic children, the pathology also manifests itself in an abundance of allergic reactions.
Why is harmony disrupted?
The autonomic nervous system operates independently of human consciousness and is engaged in extensive “economic” activities. It performs very important functions - it maintains the stability of the body’s structure, ensures the consistency of the work of internal organs and their “adjustment” to constantly changing external conditions.
At the same time, its sympathetic department, which can be called “daytime,” is responsible for activity, movement, physical activity, increases heart rate and increases blood pressure.
The parasympathetic department, the “nocturnal” one, is associated with rest, sleep, accumulation of strength and body weight. It causes a decrease in heart rate and blood pressure.
With VSD of the hypotonic type, the parasympathetic department predominates, which determines the main signs of the disease.
The main conductor of the “decisions” of the parasympathetic system into action is the vagus nerve (n. vagus, or simply vagus). It got its name due to the fact that it has endings in almost all internal organs (“wanders” through the space of the body). This is where the second name for hypotonic autonomic dysfunction comes from – “VVD of the vagotonic type.”
VSD of cerebral type
With vegetative-vascular dystonia of the cerebral type, the tone of the blood vessels in the brain is disturbed. The blood vessels spasm, which leads to disruption of blood supply and nutrition to the brain. Cells lack oxygen, and blood flow deteriorates.
The primary symptoms are headaches, dizziness, blurred vision, noise and pounding in the ears, and nausea. Other symptoms of VSD may also appear: pain in the heart, tachycardia, vascular instability (bouts of heat, sweating, pale skin), difficulty breathing, shortness of breath and a number of other symptoms. According to cardiac rhythmography data, VSD of the cerebral type will be expressed by hyperactivity of waves from the autonomic centers of the brain and, possibly, sympathetic waves.
Prevention
Timely detection, treatment and consistent prevention lead to the disappearance or significant reduction of the main manifestations of vegetative-vascular dystonia (in 80-90% of cases). A full range of measures allows you to restore the body’s adaptive capabilities. A significant role in this is played by lifestyle correction, which includes normalizing the work regime, eliminating physical inactivity, providing daily dosed physical activity, limiting excessive emotional influences, and proper nutrition. An integral component of the prevention of vegetative-vascular dystonia is rest. It is extremely important to travel outside the city regularly. The best option would be to undergo treatment in a sanatorium, a stay in which not only allows you to fully relax from constant physical and psycho-emotional stress, but also provides the opportunity to undergo special procedures in one place.

Somatoform dysfunction
With somatoform dysfunction, a person usually complains about a specific organ or group of organs that are regulated by the autonomic nervous system. These may be complaints about the cardiovascular, gastrointestinal, respiratory or genitourinary systems. The patient associates his condition with a physical disorder, but based on the results of the examination, the doctor finds no reason for it. The true cause of the malaise is a disruption in the functioning of the autonomic nerve centers. In addition to subjective localized pain, heaviness, burning or tension, specific symptoms of VSD can be easily identified among the patient’s complaints.
The variety of symptoms of autonomic dysfunction makes it difficult for the doctor to get to the root cause of the disease. Therefore, in addition to collecting anamnesis, it is important to conduct instrumental studies of the functioning of the autonomic nervous system. Find out more about diagnosing autonomic disorders.
Diagnosis of VSD
Due to the fact that the symptoms of the disease are very diverse, it is difficult to make an accurate diagnosis. It is important to take into account all the patient’s complaints, his medical history, as well as objective research data and the results of additional research methods.
Additionally, studies such as:
- Electroencephalography (EEG)
- Studies of blood vessels of the head and neck;
- ECG;
- Magnetic resonance imaging, etc.
In addition to the neurologist, the examination may involve such specialists as an ophthalmologist, otolaryngologist, cardiologist, endocrinologist, psychotherapist or psychiatrist and others.
Treatment methods
Treatment methods for neurocirculatory dystonia depend on the symptoms of the disease. NEARMEDIC specialists, first of all, conduct a thorough examination, identify chronic pathologies and provoking factors. Only then are medications prescribed to normalize heart function, sedatives, and vitamin complexes. Non-drug treatment methods have been successfully used. The appointment of physiotherapeutic procedures, as well as massage, ozone therapy, acupuncture, and water procedures helps to normalize the functioning of the entire body and relieve stress. To normalize the psycho-emotional state, conversations with a psychotherapist or psychologist are recommended.
